Deploy using Helm Chart

The Kepler Helm Chart is available on GitHub and ArtifactHub

Install Helm

Helm must be installed to use the charts. Please refer to Helm's documentation to get started.

Prometheus Setup

The Kepler Exporter requires the Prometheus Node Exporter to be installed. We recommend the Kube Prometheus Stack helm chart, which includes the Node Exporter, Grafana and other helpful stuff to provide easy to operate end-to-end Kubernetes cluster monitoring with Prometheus using the Prometheus Operator.

helm repo add prometheus-community
helm repo update

helm install prometheus prometheus-community/kube-prometheus-stack \
    --namespace monitoring \
    --create-namespace \

Add the Kepler Helm repo

helm repo add kepler
helm repo update

You can see the latest version by using the following command:

helm search repo kepler

If you would like to test and look at the manifest files before deploying you can run:

helm install kepler kepler/kepler --namespace kepler --create-namespace --dry-run --devel

Install Kepler

For Prometheus to be able to discover the metrics exported by Kepler, the serviceMonitor needs to be enabled and labeled with the release name of your Prometheus install. In our installation we called our kube-prometheus-stack install prometheus:

helm install kepler kepler/kepler \
    --namespace kepler \
    --create-namespace \
    --set serviceMonitor.enabled=true \
    --set serviceMonitor.labels.release=prometheus \

Alternatively, you can also override the values.yaml file to set these and the following values:

helm install kepler kepler/kepler --values values.yaml --namespace kepler --create-namespace

The following table lists the configurable parameters for this chart and their default values.

Parameter Description Default
global.namespace Kubernetes namespace for Kepler kepler
image.repository Repository for Kepler Image
image.pullPolicy Pull policy for Kepler Always
image.tag Image tag for Kepler Image latest Service account name for Kepler kepler-sa
service.type Kepler service type ClusterIP
service.port Kepler service exposed port 9102

Post Install

After Installation you can wait for Kepler to get ready:

    kubectl get pod \
        -l \
        -o jsonpath="{.items[0]}" \
        -n kepler
kubectl wait --for=condition=Ready pod $KPLR_POD --timeout=-1s -n kepler

and add the Kepler dashboard to Grafana:

    kubectl get pod \
        -n monitoring \
        -l \
        -o jsonpath="{.items[0]}"
kubectl cp kepler_dashboard.json monitoring/$GF_POD:/tmp/dashboards/kepler_dashboard.json

Uninstall Kepler

To uninstall this chart, use the following steps

helm delete kepler --namespace kepler
